Have you ever wanted to take enormous medium-format images with your NEX mirrorless camera? Probably not, but if you do, the Vizelex RhinoCam can make it happen. The accessory consists of a large frame, an e-mount adapter, a medium-format lens mount, and a viewfinder to help you compose your shot. In order to take a full-resolution image using the kit, you'll have to snap multiple shots in a linear array, using the frame to maneuver your NEX back and forth. The images can then be pieced together using Photoshop's automated stitching feature. The results are pretty impressive, but you'll need a lot of patience to shoot an image like this one.
As Sony Alpha Rumors points out, the method is akin to the concept of panorama stitching, but with medium-format results. The RhinoCam is compatible with either Pentax 645, Mamiya 645, or Hasselblad V lenses, and is on sale now for $499.95 through Fotodiox — super-expensive lens not included.
